In order to provide a set of field test equipment for the infrared system of modern weapon equipments and other optics instruments, a set of large-scale resistance-type infrared target system was designed. First, the large-scale infrared target was designed in modular construction. It was decomposed into several independent and controllable units. Then the working principle of the system was introduced. Three modes of thermal exchange (conduction, convection and radiation) and the computing methods for each mode were given under thermal equilibrium conditions through modeling and simulating. Periphery electro-circuit and control software were carried out as well. Finally, the performance of the system was tested. Meanwhile novel ways of temperature compensation to improve the uniformity of the surface temperature of the target was introduced. The experimental results show that the infrared target could meet test requirements for infrared imaging weaponry which wavelengths from 8 μm to 14 μm. The temperature control precision can reach 0.5ms. In conclusion, the infrared target system can satisfy requirements of reliability, high precision, as well as strong anti-jamming and stabilization.
The intelligent control of simulation target with infrared imaging target in the indoor and outdoor
environment can effectively and quantitatively evaluated the parameters such as the minimum resolution
temperature difference（MRTD）and spatial resolution of airborne forward looking infrared, infrared detection
and tracking, infrared alarm, and etc.
This paper focused on introducing the working principles of the intelligent control simulation target of
Infrared imaging target, studying the thermal radiation characteristics of the infrared target surface material,
analyzing the influences of the infrared radiation energy distribution, and developing the intelligent control
simulation target with IR imaging target for hardware-in-the-loop simulation test. The intelligent control

targets ,0.25ｍ×0.25ｍ, and 0.25m×0.5m, achieved 1℃～10℃ temperature simulation of target and the
background, and temperature control precision better than 0.5℃. Field test requirements were achieved by
